Attaching the Ascender with Securing Rope
The load (maximum 600 lb/272 kg) can be attached to the system using the carabiner attached to the lower anti-reversing
double pulley. To open the autolocking carabiner, hold carabiner with the spine in the palm of the hand, use thumb and
forefinger to rotate sleeve 1/4 turn clockwise and pull back gate with the thumb and forefinger. Insert the jaw of the
carabiner through the attachment point of the load and release the gate, the carabiner will close and lock automatically.
Check to ensure that the carabiner gate is closed and locked (FIG. a).
No person or load should be attached or suspended from the MSA Suretyman Rescue Utility
System until the ascender is attached to the operating rope (free rope) and the securing rope is
attached to the operator or secure immovable object.
WARNING
Attach securing rope to the harness of the operator or to an immovable object (FIG. 3). Hold MSA Suretyman Ascender
by the handle, use your thumb to pull down on the safety latch and pull the cam assembly fully open. The safety latch
will hold the cam assembly in the fully open position (FIG. 4). Lay the operating rope (free rope) into the channel of the
MSA Suretyman Ascender (FIG. 5). Release the safety latch with your thumb. This will close the cam assembly onto
the rope (FIG. 6).
The MSA Suretyman Ascender serves two purposes when used with the system. It provides a convenient method
of gripping the rope when pulling/hauling or holding the line. The handle is large enough to accommodate heavy gloves
or mitts and can be used with both hands (FIG. 7).
When the MSA Suretyman Ascender is attached to the operator or immovable object it acts as a brake or safety stop.
Should the operating rope be accidentally released the load will only descend the length of the securing rope. The load
will not be "dropped" or allowed to "free fall", because the securing rope and MSA Suretyman Ascender will stop the
descent (FIG. 8). The MSA Suretyman Ascender must be attached to the operating rope and the securing rope
attached to the operator or immovable object before operating the MSA Suretyman Rescue Utility System.
